Multiple reports from the supply chain indicate that the new iPhones will include a new A12 processor, made by long-time Apple supplier Taiwanese Semiconductor Manufacturing Company (TSMC). These seven-nanometer chips would be significantly smaller than the 10-nanometer A11 processors currently in iPhone X and iPhone 8 lineup. They will also apparently be 10-percent faster, according to benchmark tests uploaded to Geekbench back in June. Updated chip technology could also make the new iPhone devices use battery power more efficiently.

Those benchmarks also indicated that the OLED iPhone devices will come with 4GB of RAM, up from the 3GB in the iPhone X. Analyst Ming-Chi Kuo has backed up this information and added that the OLED devices will also come with an L-shaped, two-cell battery similar to the one in the iPhone X, and thanks to the larger size, the larger 6.5-inch device will sport a 25-percent larger battery capacity than the iPhone X, perhaps as big as 3,400 mAh. The cheaper, LCD device will reportedly stick with 3GB of RAM and a rectangle-shaped battery similar to what’s in the iPhone 8 lineup.
